Connection requests that read like you did the homework
Export from Sales Navigator, get an opener per prospect that references their company — short enough for a connection note, specific enough to earn the accept.
300-character connection notes force economy
The 25-word cap isn't a limitation here — it's exactly the length a LinkedIn note needs.
'I'd love to add you to my network' is invisible
Recruiters and SDRs send millions of those a day. One specific observation about the prospect's company clears the bar instantly.
Multi-channel sequences need consistent personalization
Use the same first_line column in the email step and the LinkedIn step so the story matches across channels.
How it works
Export leads from Sales Navigator (or paste name/company/website)
Include the LinkedIn URL column — it's picked up automatically
Generate with the warm tone (it fits LinkedIn best)
Paste each line into the connection note or your automation tool's variable

Common questions
Does ColdOpen scrape LinkedIn?
No. It works from the CSV you provide and the company's public website — no LinkedIn scraping, no ToS risk on your account.
Are the lines short enough for connection notes?
Yes — every line is capped at 25 words, comfortably inside LinkedIn's 300-character note limit.
What does it cost?
First 10 lines free, then $19 once for unlimited. You bring your own OpenAI or Anthropic key, which stays in your browser and costs you fractions of a cent per line.
